Fixed Deposit Calculator (Sri Lanka)
Enter your FD amount, interest rate and tenure to see maturity value or monthly interest instantly.
How this fixed deposit calculator works
For "at maturity" FDs the calculator applies monthly compounding: Maturity = P × (1 + r/12)ⁿ, where P is your deposit, r is the annual rate, and n is the number of months. For monthly-interest FDs it computes Monthly interest = P × r / 12 and shows total interest paid across the tenure. Withholding tax is not deducted in this figure — banks deduct it at source when they credit interest.
Typical FD rates in Sri Lanka (2026)
Licensed banks (BOC, People's Bank, NSB, Commercial, HNB, Sampath, DFCC) currently pay 8–11% for 1-year FDs. Licensed finance companies (LOLC, LB Finance, Central Finance, People's Leasing) pay 10–13% with higher senior citizen rates. Rates fluctuate with the CBSL policy rate — during easing cycles FD rates fall quickly, so locking in longer tenures during a tightening cycle can pay off.
Tips to get the best FD return
Compare rates on Findit.lk before renewing — even a 1% difference on a Rs. 1M FD is Rs. 10,000 per year. Use senior-citizen and staff schemes if eligible. Ladder your FDs (split into 3-, 6-, 12-, 24-month deposits) so you always have some maturing without breaking any early. Keep the balance under the Rs. 1,100,000 deposit insurance limit per institution.
FD vs government treasury bills
Government T-bills and T-bonds often pay similar or better yields than bank FDs and are effectively risk-free. You can buy them via any primary dealer or licensed bank. For serious savers with over Rs. 500,000, T-bills are worth comparing alongside FDs.
Frequently Asked Questions
What is the current FD interest rate in Sri Lanka?

Which bank has the highest FD rate in Sri Lanka?

Monthly interest FD or at-maturity — which is better?
At-maturity FDs give a higher effective yield because interest compounds within the deposit. Monthly interest FDs pay you a fixed income each month but the underlying rate is slightly lower. Pick monthly interest if you need regular income; pick at-maturity if you're saving to grow the capital.
Is FD interest taxed in Sri Lanka?
Yes. Banks and finance companies deduct 5% withholding tax (WHT) on FD interest at source in Sri Lanka in 2026. If your total income exceeds the personal relief threshold, additional PAYE may apply.

Can I break my fixed deposit early in Sri Lanka?
Yes, most banks allow early withdrawal but reduce the interest rate — usually to the savings rate or the shortest applicable FD rate, minus a penalty. If you might need the money, split into multiple smaller FDs so you only break one, not the whole amount.
Is my FD safe in a Sri Lankan bank?
Yes. Deposits in licensed banks are covered by the Sri Lanka Deposit Insurance and Liquidity Support Scheme (SLDILSS) up to Rs. 1,100,000 per depositor per institution. For larger amounts, spread across multiple licensed institutions to keep every rupee within the insured limit.
